Viber와 WhatsApp 비교

전화번호로 전화

Viber Out: 실제 전화번호로 전화를 걸어요. WhatsApp: 자체 사용자에게만 연락 가능. 이는 단순히 정도의 차이가 아니에요. 자기 서비스의 다른 설치 사용자에게만 연결되는 앱은 전혀 다른 제품이에요. 상대방이 유선전화를 쓰거나 스마트폰이 없거나 아무것도 설치하지 않으려 한다면, 가격이 더 저렴해도 대안이 될 수 없어요. 먼저 이 점을 확인하세요. 두 서비스가 실제로 통화하려는 번호에 연결될 수 있을 때만 아래의 모든 내용이 의미가 있어요.

과금 단위

Viber Out은(는) 올림 적용 방식으로 청구하고, WhatsApp은(는) 앱 간 통화만 가능 방식으로 청구해요. 분당 요금이 같아도 최종 청구액은 달라지며, 대부분의 사람이 통화하는 구간에서 그 차이가 가장 커요. 35초 통화를 1분으로 올림하면 해당 통화에 약 70퍼센트의 추가 요금이 붙지만, 요금 자체가 바뀐 것은 아니기 때문에 어떤 요금 비교표에도 나타나지 않아요.

구독

Viber Out: 구독 제공. WhatsApp: 구독 없음. 구독은 손익분기점을 넘기면 분당 요금이 더 저렴하지만, 그렇지 않은 달에는 매번 더 비싸요. 따라서 구독을 선택하는 것은 앞으로 자신의 사용 방식을 예상해 내리는 결정이에요. 선불 크레딧은 그 반대예요. 약정이 없는 대신 단가가 더 높아요.
